Hi, I want to annotate values in llvm, like making a flag for the operands and result of an instruction for future use. I wonder if there's any interface to do such a thing? Thanks! -- Shuhan

Hi: I want to pass some message of instructions from LLVM Internal representation to backend code. For example, I make a flag for some certain operands of certain instructions. How can it be passed to the backend instructions? Which programs I should look into? Would someone give me some idea? Thank you ! -- Shuhan

Hi: I have extended the IR for adding flag. But I just want this flag to pass through the backend machine code. I know there're several passes like register relocation, schedualing, etc. But I think I just miss the part which is used to "parser" the LLVM IR to machine code instructions. Would you give me some help? Thank you ! > On Sun, 10 Jul 2005 shding at mtu.edu wrote:

Hi, I'm changing bytecode format a little bit, i.e. for 2 operands Instructions, the original is like this: 01-00:Opcode type 07-02:Opcode 15-08: Instruction type 23-16: Operand#1 31-24: Operand#2 My change is like this: 01-00:Opcode type 07-02:Opcode 15-08: Instruction type 16: myflag1 17: myflag2 24-18: Operand#1 31-25: Operand#2 I do

I'm a new guy for llvm. I'm doing a project in which some instructions should be moved from one block into another. Those instructions may be data-dependent. When I tried to delete them one by one, it cause the error message like, " use stuck around after a def is destroyed" even if I deleted the use befor the def. When I tried to add them to another block, errors occurred like

I just updated again (both llvm and llvm-gcc). The only thing that changed was: P test/Regression/CFrontend/2005-12-04-DeclarationLineNumbers.c The regression test below was done *with* your llvm-gcc changes to llvm- expand.c. I don't know what the failures are all about, but I will try it again. If its the same, I'll let you know. Reid. On Thu, 2006-04-13 at 16:20 -0500, Chris Lattner

Hi, In the directory of lib/CodeGen/SelectionDAG, I cann't find SelectionDAGISel.cpp. I only have DAGBuilder.cpp and SelectionDAG.cpp. I don't know why. My edtion is 1.4. Is it because of the edtion difference? Thanks! > On Mon, 11 Jul 2005 shding at mtu.edu wrote: >> I have extended the IR for adding flag. But I just want this flag to >> pass through the backend

As the title. Thank! -- Shuhan

Hi: For some reason, I changed the files /ByteCode/Writer/Writer.cpp and /ByteCode/Reader/Reader.cpp and I introduced an new version number 6. Now I replaced these two changed files with the original ones that are version 5. And I rebuild the llvm compiler. What make me mad is that the bytecode produced now is still version 6! Of course the reader cannot recognize it because the current reader

Thank you. I'm only consider about how the compiler comiles c program to LLVM IR. I know there should be a scanner, parser, and IR generator. But where is the main entrance and how about the flow of the process, especially about the IR generator? > shding at mtu.edu wrote: >> Hi, >> Where can I find the main function of llvm compiler in the source >> file? >>

Hello, The interface is named Annotation and it allows any Annotable object to be annotated. Note that the Value class is an Annotable. HOWEVER, if the annotation information is something that might be useful to other developers or to other analysis/transformation passes, you're strongly encouraged to create an Analysis instead. See the various analyses in include/llvm/Analysis for examples.

Hi, When compiling the cfrontend for Linux/PPC architecture on a powermac G5, i got the following error : -------------------------------Compilation error listing if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi make GCC_FOR_TARGET="/usr/local/home/cyrille/project/llvm/cfrontend/build/gcc/xgcc -B/usr/local/home/cyrille/project/llvm/cfrontend/build/gcc/

If you're talking about the llvm-gcc and llvm-g++ compilers (C/C++ to LLVM) then they are in the downloadable tarballs available here: http://llvm.cs.uiuc.edu/releases/. You

Your output looks like gccas is being given a native code assembly language file to parse, and I seem to recall that that happens if

Hi: When I tried to use llc -march=sparcv9 to compile some llvm .bc to SparcV9, I got such error: llc: /llvm/lib/Target/SparcV9/SparcV9RegInfo.h:62: virtual void llvm::TargetRegClassInfo::markColorsUsed(unsigned int, int, int, std::vector<bool, std::allocator<bool> >&) const: Assertion `UserRegType == RegTypeWanted && "Default method is probably incorrect for

Hi: In the file of SparcV9BurgISel.cpp, you said you didn't implement the "Switch" instruction and I also can't find how the "Select" instruction is implemented. So do you do some work to handle these two kind of instructions in other parts? Where can I find it? Thank you! -- Shuhan
